<S. M. Kreidenweis> coauthored a hygroscopicity framework with <M. D. Petters> for relating aerosol water uptake to cloud-condensation activity. The framework balances solute effects with the curvature contribution to droplet <vapor pressure>.
A particle's dry diameter and hygroscopicity jointly affect its activation threshold. Thus two equally sized particles need not form cloud droplets at the same <supersaturation> if their compositions differ.<A single parameter representation of hygroscopic growth and cloud condensation nucleus activity by M.
